MJ7006 fisheye lens,introduction to the application of UAV visual obstacle avoidance technology
UAV obstacle avoidance technology refers to the technology of obtaining surrounding environment information through cameras and other sensors to avoid collisions of UAVs.The basic principle is to process and analyze the collected images or sensor data to identify the obstacles in front of or around the drone,and calculate the route of the drone through an algorithm,so that it can autonomously avoid obstacles objects and continue flying safely.
UAV visual obstacle avoidance technology usually adopts the following methods:
Computer vision:By using the camera to collect images around the drone,and then process and analyze the images to identify the position and size of obstacles ahead.For example,machine learning algorithms are used to identify different types of obstacles,thereby providing more accurate obstacle avoidance guidance for drones.
2.Lidar:Lidar can scan the surrounding environment to obtain high-precision three-dimensional map information.Through processing and analyzing the map information,it can identify obstacles in front of or around the drone and calculate a safe flight route.
3.Ultrasonic sensor:The ultrasonic sensor can measure the distance between the drone and surrounding objects,thus helping the drone to avoid obstacles.Due to the low accuracy of ultrasonic sensors,they are usually used as auxiliary sensors.
UAV visual obstacle avoidance technology is an important guarantee for the flight safety of UAVs.It can improve the flight autonomy and reliability of UAVs and make them more suitable for various application scenarios.For example,in the fields of logistics distribution,agricultural plant protection,oil exploration and other fields,UAV visual obstacle avoidance technology can greatly improve the work efficiency and safety of UAVs.
ShengQiang Optoelectronics has developed a 2.7mm F2.8 170°M8 fisheye lens,which has the characteristics of small size,light weight,and large angle.It has been successfully used in UAV visual obstacle avoidance.By installing the 210°M8 fisheye lens in four directions to achieve image acquisition without dead angle.The image is processed to give movement instructions to bypass obstacles.With the satellite positioning system,it can automatically cruise and cooperate with the ground station for image big data analysis.
